High prevalence of frailty in end-stage renal disease.

ABSTRACT:

Purpose

Prognosis of the increasing number of elderly patients with end-stage renal disease (ESRD) is poor with high risk of functional decline and mortality. Frailty seems to be a good predictor for those patients that will not benefit from dialysis. Varying prevalences between populations are probably related to the instrument used. The aim of this study was to measure the prevalence of frailty among ESRD patients with two different validated instruments.

Methods

This cross-sectional study was conducted among patients, aged ?18 years, receiving hemodialysis, peritoneal dialysis and pre-dialysis care between September 2013 and December 2013 in a single dialysis center in Apeldoorn, the Netherlands. Frailty was measured with the frailty index (FI) and frailty phenotype (FP).

Results

Prevalence of frailty by the FI was 36.8 % among 95 participants with ESRD (age: 65.2 years, SD ± 12.0). Frailty prevalence among participants aged ?65 and <65 years was 43.6 and 27.5 %, respectively. Female sex [odds ratio (OR) 3.3, 95 % confidence interval (CI) 1.3-8.0] and a Charlson comorbidity index score of ?5 (OR 2.6, 95 % CI 1.0-6.6) were associated with frailty. The FI identified different but overlapping participants as frail compared with the FP; 62.5 % of frail participants according to FI were also frail according to the FP.

Conclusions

Prevalence of frailty among young and elderly ESRD patients is high; being female and having more comorbidity was associated with frailty. Use of a broader definition of frailty, like the FI, gives a higher estimation of prevalence among ESRD patients compared with a physical frailty assessment.

Project description:OBJECTIVE:Serum albumin is a marker of malnutrition and inflammation and has been demonstrated as a strong predictor of mortality in chronic kidney disease (CKD) and end-stage renal disease (ESRD) patients. Yet, whether serum albumin levels in late-stage CKD are associated with adverse outcomes after the transition to ESRD is unknown. We hypothesize that lower levels and a decline in serum albumin in late-stage CKD are associated with higher risk of mortality and hospitalization rates 1 year after transition to ESRD. DESIGN AND METHODS:This retrospective cohort study included 29,124 US veterans with advanced CKD transitioning to ESRD between 2007 and 2015. We evaluated the association of pre-ESRD (91 days before transition) serum albumin with 12-month post-ESRD all-cause, cardiovascular, and infection-related mortalities and hospitalization rates as well as the association of 1-year pre-ESRD albumin slope and 12-month post-ESRD mortality using hierarchical multivariable adjustments. RESULTS:There was a negative linear association between serum albumin and all-cause mortality, such that risk doubled (hazard ratio [HR]: 2.07, 95% confidence interval [CI]: 1.87, 2.28) for patients with the lowest serum albumin <2.8 g/dL (ref: ?4.0 g/dL) after full adjustment. A consistent relationship was observed between serum albumin and cardiovascular and infection-related mortality, and hospitalization outcomes. An increase in serum albumin of >0.25 g/dL/year was associated with reduced mortality risk (HR: 0.76, 95% CI: 0.63, 0.91) compared with a slight decline in albumin (ref: >-0.25 to 0 g/dL/year), whereas a decline more than 0.5 g/dL/year was associated with a 55% higher risk in mortality (HR: 1.55, 95% CI: 1.43, 1.68) in fully adjusted models. CONCLUSIONS:Lower pre-ESRD serum albumin was associated with higher post-ESRD all-cause, cardiovascular, and infection-related mortalities and hospitalization rates. Declining serum albumin levels in the pre-ESRD period were also associated with worse 12-month post-ESRD mortality.

Project description:BackgroundPrevious studies have demonstrated that early pre-end-stage renal disease (ESRD) nephrology care could improve postdialysis prognosis. However, less is known about the specific types of interventions responsible for the improved outcomes. We hypothesized that more frequent predialysis laboratory testing is associated with better postdialysis outcomes in incident ESRD patients.MethodsIn all, 23?089 patients with available outpatient laboratory tests performed during the 2-year predialysis (i.e. prelude) period were identified from a total of 52?172 American veterans with chronic kidney disease (CKD) transitioning to dialysis between October 2007 and September 2011. The associations between the frequency of combined laboratory tests, including serum creatinine, serum potassium and hemoglobin (test trio), with postdialysis mortality and hospitalization were examined in multivariable adjusted Cox and logistic regression models.ResultsWhen entering the 2-year prelude period, the mean age (Standard Deviation) of the patients was 66.2 (SD 11.3)?years and the mean estimated glomerular filtration rate was 46.8 (SD 23.9)?mL/min/1.73 m2. In all, 14% of patients had the test trio performed less than twice in 24?months and 8.9% had the trio measured more often than every other month. Over a 2.5-year median postdialysis follow-up period, 15?303 (66.3%) patients died (mortality rate 260/1000 patient-years). The adjusted hazard ratio of all-cause mortality and adjusted odds ratio of the composite of hospitalization or death associated with lab testing done >12/24?months compared with 2-?4/24 months were 0.68 [95% confidence interval (CI) 0.65-0.73] and 0.70 (95% CI 0.62-0.79), respectively.ConclusionsMore frequent laboratory testing in patients with advanced CKD is associated with better clinical outcomes after dialysis. Further examination in clinical trials is needed before the implementation of more frequent laboratory testing in clinical practice.
